Thanks for your answer but that's not good for what I want to do.
I have no problem in integrate Facebook feed.
What I want to do, is integrate Facebook reviews, https://www.facebook.com/pg/GitesLaBrejoliere/reviews/?ref=page_internal
And I really don't know how to do that, because in Page Plugin - Social Plugins - Documentation - Facebook for Developers I can't have reviews page.
After doing some research I found that there are already many widgets available for Wordpress, however, didn't find one for Muse.
You may see this thread from facebook community - Is there a way to post your Facebook reviews from your Page to your website?
